Lombok is a java library that you can plug into your editor which will automatically generate code in .class file instead of in source file. E.g:   getters, setters toString, equals, hashcode, builder, loggers, and many others. In this tutorial, I’ll talk about configuring it in two of the most popular IDEs- IntelliJ IDEA and Spring Tool Suite. Check my Github repo to learn project Lombok using java source code. Note: Step for installing the plugin for Eclipse and Spring tool Suite (STS) are the same. Steps to configure Lombok in STS Download Lombok jar from the Lombok site.

Once selected, click on Install/update button and you are done. Steps to configure Lombok in IntelliJ IDEA Open IntelliJ Idea and click on File-> Settings… Click on Plugin opt...

Remote debugging is a way of debugging any process running on some other location from your development machine. Local debugging is the best way in my opinion and should always be preferred over remote debugging but if local debugging is not possible and there is no way to debug your process then remote debugging is the solution. Many of us work on a project which runs on Linux operating system and we do development mostly on Windows. Eclipse provides us most useful feature called " Remote debugging " by using which you can debug your Linux running process from your windows machine. Now let's see how we can setup remote debugging in Eclipse: Just take a example of a simple program that we want to be debugged: package com.tutoial.debugger; /**  * @author abdul  *  */ public class Debug {     public static void main(String args[]) {         for(int i=1; i<=10;i++) {      ...

I’ve been working with OSGi for quite awhile and have faced a problem "Workbench has not been createt yet" issues. I was getting this error, When i was trying to run OSGI plugin from Eclipse and I guess many of you must have face this problem. So i am writing a little bit about how to resolve this issue so others don’t repeat the same mistakes. From a good article on eclipsezone: java.lang.IllegalStateException: Workbench has not been created yet This usually comes when someone tries to run a Java application against an OSGi bundle with java -classpath .... . It really means that the workbench plug-in hasn't started yet, and so calls to getWorkbench() fail. This is essentially a race condition, and can be solved by either expressing an explicit dependency on that bundle or bumping up that bundle to a higher start level than the workbench. Generally not seen, but if it is, that's what's happening. Now to set the bundle to a higher start level than the work...

The ADT has a few such annoying bugs. But you can sort them out.. What usually helps is: 1. Close Project->Open Project > Build Automatically . 2.Another thing that sometimes helps is right click project > android tools > fix project properties and remove unnecessary content or jar files. 3.Or you can do Project->clean and Refresh . If still it not generating R.java files then check your class there must be a extra line.. Import R.java.*; Remove that and then do all the above one by one.. Hope it help .. If someone know other way please let me know. T...
